What causes black mold on plants?

Sooty mold infection, which produces black, soot-like spots on your plants' foliage, comes from honeydew – and not the good kind of honeydew. This type of “honeydew” refers to a sticky syrup excreted by the terminal opening in a bug's gut when it eats too much of your plants' sap. Basically, it eats until it pops.

What is a good insecticidal soap?

Fill a 1-gallon jug with water—either distilled or tap, as long as yours is not hard water (hard water reduces the effectiveness of insecticidal soap)—and leave a couple of inches at the top. Then add 2-½ tablespoons liquid dish soap (Dawn or liquid castile soap are good choices) and 2-½ tablespoons vegetable oil.

Why do plant leaves turn black?

Improper watering causes plants leaves to turn black and drop prematurely, but this can happen if you water too much, and can also happen if you water too little. Ensure the soil around the plant remains evenly moist at all times, and when the top 1 to 1 1/2 inches of the soil feels dry, you know you're good to water.
